abstract = "An austenitic metal-cored wire (diameter – 1.6 mm) with additional nitrogen alloying (0.25–0.40 wt.%) was developed for this study. Mechanical tests and metallographic studies of the deposited metal and welded joints made with austenitic metal-cored wire (composition – Cr20Mn5Ni4Mo2.5Cu3N0.3) were conducted. It was found that the values of σu and σ0.2 of the deposited metal obtained by using the developed wire were 20 to 30% higher compared to the utilized electrode materials, while the ductility characteristics were preserved (δ = 43%). It was shown that the use of metal-cored wire (Cr20Mn5Ni4Mo2.5Cu3N0.3) for welding of high-strength steel 20HGSNM (EN 1.6523) makes it possible to obtain defect-free welded joints with austenitic-ferritic structure, which have 20% higher strength characteristics compared to the analogues.",
